A cannonball of mass 27.6 kg is shot into the air at an angle of 45 degrees with respect to horizontal. At the top of its ballistic trajectory, the cannonball suddenly explodes into two separate pieces, a smaller piece this is 1/3 the original mass, and a larger piece that is 2/3 the original mass. The smaller piece ends up landing right back at the spot where the cannonball was originally launched, 14.7 seconds after it was launched. How far...
At an Independence Day celebration show, a large firework is shot from the ground and, in the first stage of its bursting pattern, splits into two unequal parts. Assume that the firework has a mass of m_o = 0.30 kg and is launched from a cannon at an angle of theta_o= 48.8° with an initial velocity of v= 20 m/s. Just as the firework reaches its hight point in its trajectory, it explodes into two pieces. Immediately after the explosion,...
A mortar fires a shell of mass m = 1.79 kg at speed v0. The shell explodes at the top of its trajectory (shown by a star in (Figure 1)) as designed. However, rather than creating a shower of colored flares, it breaks into just two pieces, the smaller one of which has a mass 0.240 kg . If there had been no explosion, the shell would have landed a distance r = 172 m from the mortar. Both pieces land at...
An object with total mass mtotal = 6.4 kg is sitting at rest when it explodes into two pieces. The two pieces, after the explosion, have masses of m and 3m. During the explosion, the pieces are given a total energy of E = 45 J. What is the speed of the smaller piece after the collision? What is the speed of the larger piece after the collision? If the explosion lasted for a time t = 0.029 s, what...
Suppose a 11.0 kg fireworks shell is shot into the air with an initial velocity of 72.0 m/s at an angle of 80.0° above the horizontal. At the highest point of its trajectory, a small explosive charge separates it into two pieces, neither of which ignite (two duds). One 9.00 kg piece falls straight down, having zero velocity just after the explosion. Neglect air resistance (a poor approximation, but do it anyway). Calculate the velocity (in m/s) of the 2.00...
A mortar fires a shell of mass m at speed v0. The shell explodes at the top of its trajectory (shown by a star in the figure) as designed. However, rather than creating a shower of colored flares, it breaks into just two pieces, a smaller piece of mass 15m and a larger piece of mass 45m. Both pieces land at exactly the same time. The smaller piece lands perilously close to the mortar (at a distance of zero from...
Question 19 This question contains multiple parts. Make sure to read all the instructions and answer each part. (408553) {2D Inelastic Collisions} At an Independence Day celebration show, a large firework is shot from the ground and, in the first stage of its bursting pattern, splits into two unequal parts. Part a (1 points) Assume that the firework has a mass of m0=0.30 kg and is launched from a cannon at an angle of θ0 =35.5 degrees with an...
Please do 1a 1b 1d and 1E and show work, thank you! 1.) A ball with mass 5.0 kg is launched upwards towards the east into the air with a speed of 15. m/s at an angle of 30 degrees to the ground. Note: For this question the motion is fully three-dimensional. Orient your axes so that the positive y-axis points north, the positive X-axis points east, and the positive z-axis points upwards (towards the sky. 1A.) If a gusting...
was trying work on this homework but can’t seem to get it right the ball and the pendulum cup have the same velocity after the collision. As is the case with any collision, total momentum is conserved (unchanged). Using conservation of momentum, write down an equation for Vealefore in terms of the velocity of the hall together with the pendmcu ( d the mass of the al and that of the cup (meup). ball before= Using conservation of energy between...
